Find the energy contained in standard battery sizes Yes, we said farads, not microfarads. As such it can store 277 Joules at 2.5 volts. This is not a great amount of energy storage, hence the limited discharge time. However, it can deliver more peak current than a lead-acid battery of the same size, and it recharges easily more than 500,000 times.

joule The joule (pronounced DJOOL) is the standard unit of energy in electronics and general scientific applications. One joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter. One joule is the equivalent of one watt of power radiated or dissipated for one second. In some applications, the British thermal unit (Btu) is used to express energy.

Energy, Plants & Man Answer by Knapp1. Confidence votes 23.0K. 1 coulomb is the electric charge carried in 1 second by a current of 1 amp. 1 joule is the work done in one second at a power of 1 watt.So they are different things, with different dimensions, you can't equate them.y definition a volt is a joule per coulomb, V=W/Q (V is voltage, W is work done or energy measured in joules, Q is charge measured in coulombs) therefore 1 volt is 1 joule pe … r 1 coulomb of charge (1C of charge is a very large amount to expect to see very small numbers for charge).

- Multiple watts by seconds to get joules. A 1 Watt device consumes 1 Joule of energy every 1 second. If you multiply the number of watts by the number of seconds, you'll end up with joules. To find out how much energy a 60W light bulb consumes in 120 seconds, simply multiply (60 watts) x (120 seconds) = 7200 Joules. 1  This formula works for any form of power measured in watts, but electricity is the most common application.

Energy Levels of Electrons The x-axis shows the allowed energy levels of electrons in a hydrogen atom, numbered from 1 to 5. The y-axis shows each level's energy in electron volts (eV). One electron volt is the energy that an electron gains when it travels through a potential difference of one volt (1 eV = 1.6 x 10 -19 Joules).Click on the image for a larger view. Electrons in a hydrogen atom must be in one of the allowed energy levels.If an electron is in the first energy level, it must have exactly -13.6 eV of energy. If it is in the second energy level, it must have -3.4 eV of energy. An electron in a hydrogen atom cannot have -9 eV, -8 eV or any other value in between.Let's say the electron wants to jump from the first energy level, n = 1, to the second energy level n = 2.he y-axis shows each level's energy in electron volts (eV).

- (kJ/mol, kJ.mol-1) A Joule, J, is the SI unit of energy and is defined as one kg.m2/s2. The prefix kilo means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence per mole.
